To all whom itmay concern: Be it known that I, LESLIE S. HACKNEY, of St. Paul, Ramsey county, Minnesota, have invented certain new and useful Improve ments in Ventil'atin Devices, of which the followin is a specil ation.

In rai way coaches, particularly those of the parlor sleeping car type where double, tight-fitting windows are employed, the need of some ventilating apparatus other than those provided in the roof of the car, has been generally recognized. The windows are usually closed to revent the entrance of cinders, smoke and ust, and the interior of the car, particularl at night, becomes very close and stifling. fiany passengers who would prefer to admit fresh air through the windows cannot do so on account of the draft and the danger of takin cold. This is particularly true. as regar s the upper berths ventilators when open tends to admit drafts of air directly upon the person in the berth. I

To overcome these objections to railway coaches. generally and and sleeping cars, and to remove one of the discomfortsand annoyances of traveling, is the object of m present invention.

A further Ob ect is to provide a ventilating apparatus of simple, compact construction, ca able of application to any type or make 0 railway coach.

The invention consists generally .in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification, the figure represents a longitudinal vertical sectional view of one end of a railway coach with my.invention applied thereto.

In the drawin a sleeping car an 3 the side walls of the car. Under the seats 4.- I provide'a series of re isters 5- leading to a pipe 6 arranged within the wall near the floor line and extending from end to end of the car. This pi eenters the lower end of a pump cylinder 7, and a pipe 8 leads from the pump cylinder down through the floor of the car to a point where the foul air collected in the pipe 6 through be discharged. Check the registers 5 may provided in these pipes valves 9 and 10 are by means of which throu h is controlled, one opene as the other closes.

walls of the car is a pipe 11 extending lengthcharged into the car and into the upper and lower berths when made up. These registers mayrbe adjusted to regulate the admission of the air. The pipe 11' extends to a chamber 15 inclosing an ice-box 16, and a pipe 17 leads from the ice-box to the upper end of the cylinder 7 and communicates with the o en air through a e 18 provided with a c eck valve 19 w 1c opens when the plunger descends and closes when it ascends. Through the pipe 18 the pure fresh air is taken into the car. A lunger 20 is provided within the pump cy inder and a driving mechanism 21 is connected to the pump plunger and is operated from an electric motor 22 or other suitable ower. A valve 23 is provided in the pipe 1 and a spout 24 exten s from the ice-box 16 through the chamber 15 to a water tank 25. The pipe 17 communicates also witha box 26 wherein a radiator 27 is arranged, and pipes 28 and 29'connect the pipe 17 and the box 26 with the pipe 11. A valve 30 is provided at the junction of the pi cs 28 and 17. I am thus able to direct the resh pure air through the chamber around the ice-box 16 and through the box 26 at will and cool the air. or heat it before discharging itinto the car. By closing the valves 23 and 30 leading to the ice-box or radiator, I can deliver fresh air to the pipe 11 through pipes 17 and 26 without cooling or heating it.

I This apparatus mav be arranged w1th1n a small compartment adjoining the wash room of the car where it is easily accessible for the purpose of operation and control.

I prefer to provide a thermostat for controlllng the valves. of the heating and ventilating apparatus, the thermostat proper being indlcated by reference numeral 23 and arranged on the wall of the car at a suitable distance from the floor. ThlS thermostat is connected by the usual wires (not shown), with motors M and M arranged near the pipes of the heatmg ventllatin apparatus and connected by a suitable cran mechanism with the valves 30' and 23. These connections are so adjusted that the oper ation of one motor will direct the supply of air through the cooling tank, and the operation of the other motor will direct the a1r through theheating radiator. I am thus foul air'eduction pipe having inlet enings able to control the supply of the cool and along the lower portion of said cham r and warm air to the car according to the temopening into the pump on one side thereof, 5 perature of the car. v a foul air discharge pipe leading out from" 5 I have shown this device in connection the same end of the cylinder, a fresh air with a sleepin car but do notwish tobe inlet pipe opening into the oppos'te side of confined to su useas the invention is cepehe pump, a fresh air supply ipe leading ble of application on tram or traction cars from the fresh air inlet side of t e pump and 40 of all kinds and in the staterooms of steam extending throu h 'said chamber along the 10 ships and in buildings of various descripupper portion hereof and provided with tions. downwardly extending branches opening I claim as my invention into the upper and middle portions of the 1.
